Metabolite Identification

Common Name

L-Threoneopterin

Description

L-Threoneopterin is a catabolic product of GTP. It is synthesized by macrophages upon stimulation by interferon-gamma. It is used as a marker of HIV infection. It belongs to the chemical group known as pterins. Neopterin is a pteridine derivative present in body fluids; elevated levels result from immune system activation, malignant disease, allograft rejection, and viral infections (From Stedman, 26th ed). Neopterin also serves as a precursor in the biosynthesis of biopterin.
